SCALING ALARM SETPOINTS	This section is for users who do not have SMS and must set up alarms from
	the circuit monitor display. It explains how to scale alarm setpoints.
	When the circuit monitor is equipped with a display, the display area is 4 x 20
	characters, which limits the displaying of most metered quantities to five
	characters (plus a positive or negative sign). The display will also show the
	engineering units applied to that quantity.
	To determine the proper scaling of an alarm setpoint, view the register
	number for the associated scale group. The scale factor is the number in the
	Dec column for that register. For example, the register number for Scale D to
	Phase Volts is 3212. If the number in the Dec column is 1, the scale factor is
	10 (101=10). Remember that scale factor 1 in Table 6–1 on page 91 for Scale
	Group D is measured in kV. Therefore, to define an alarm setpoint of 125 kV,
	enter 12.5 because 12.5 multiplied by 10 is 125. Below is a table listing the
	scale groups and their register numbers.
	Table 6–2: Scale Group Register Numbers
	Scale Group	Register Number
	Scale Group A—Phase Current	3209
	Scale Group B—Neutral Current	3210
	Scale Group C—Ground Current	3211
	Scale Group D—Voltage, L–L	3212
	Scale Group E—	3213
	Neutral Voltage, L–N, N–G
	Scale Group F—Power kW, kVAR, kVA	3214
